Class ReportingDataManager

java.lang.Object
com.bea.wli.reporting.ReportingDataManager

public class ReportingDataManager

extends java.lang.Object

ReportingDataManager is a server-local singleton object that keeps registry of reporting providers (a reporting provider implements ReportingDataHandler). It provides operations to add and remove reporting data handlers in addition to operation to export/handle reporting data stream.

Example:

Registering a reporting provider ...

 import com.bea.wli.reporting.*;
 ...

 ReportingDataManager rmgr = ReportingDataManager.getManager();
 MyReportingDataHandler myH = new MyReportingDataHandler();
 rmgr.addHandler(myH);
 
 

Unregistering a reporting provider...

 rmgr.removeHandler(myH);
 

If the provider is deployed in the form of a J2EE Application, addHandler and removeHandler methods could be called in postStart and preStop operations respectively of an implementation of weblogic.application.ApplicationLifeCycleListener in the application.

Method Detail

getManager

public static ReportingDataManager getManager()

Get server-local singleton reporting data manager

Returns:

ReportingDataManager server-local singleton

shutdown

public void shutdown()

Shutdown removes and closes all Handlers

addHandler

public void addHandler(ReportingDataHandler handler)

Add a reporting data handler to receive reporting data. If there are more than one handlers added, the reporting data would be sent to handlers in the same sequence in which handlers are registered. An implementation of ReportingDataHandler is typically called a provider.

Parameters:

handler - reporting data handler to add

removeHandler

public void removeHandler(ReportingDataHandler handler)

Remove the specified reporting data handler. Returns silently if the given handler is not found or is null.

Parameters:

handler - reporting data handler to remove

ReportingDataHandler

getHandlers

public ReportingDataHandler[] getHandlers()

Get all handlers registered. The handlers are returned in the same sequence in which they are registered using the addHandler method.

Returns:

an array of reporting data handler

s - reporting data

Throws:

java.lang.Exception - in case of failure to handle this reporting event
